acclaim. A (01.'164-112i e whether arranged in open rectangularformation yThe present invention relates to a slotting maf chine and is:more particularly directed to cer-4 `tainfnevv and useful improvementsincorporated in a machine which is adapted forfnotchins perindexingsystems or the like.

forated cards of There are numerous cards on the market of var-` ioussizes which are peripherally perforatedr in a manner as to segregatecertain groups of perultimately notching out certain of theseperforatlons to thereby code these cards in direct relation to theinformation that is written upon the card or collaterally obtained andrelating thereto during the usual course of` business. Briefly,therefore, these cards provide an efficient and simple means for.

lclassifying the data'contained thereon and by subsequently employingvarious types of needle selectors, it is possible toquickly sort thecards n according to certain classifications or 'according to certaininformation which shall be common to the selected group of cards. Forthe purpose of demonstrating the present invention, the machine hereinshown and described has been kadapted for use-in connection with a, cardof rectangular shapel and measuring 31/4 inches'wide r and Il/zincheslong. This particular size of card has been selected for the simplereason that a card of this size seems to be broadly used and" might betermed a standard card" for the purposes of explanation. l

There are a number of improvementsresulting in rdefinite advantageswhich are incorporated in the present machine and one ofthe main objectsVof the latter is" to provide a plurality of punches arranged 'in arectangle for the purposer of operav,tively notching a ,perforated cardalongfany edge l or any one or more edgesthereof in one simultaneouspunching operation. Obviously, one or more punches may beibrought intosuch operativerelation depending directly upon the selection of punchesmade in accordance with the information to be contained upon eachlparticular `card. 'I'he Lcards rto be notched for coding are usuallyplaced where each card may be viewed` by the operator and inthe presentmachine the In the ma ykeys are arranged y to code the card in then thiscard will be ejected ies shall be advanced into 4of the card to toimitate the general lines of the index card perforations or wherein thekeys may be arranged or positioned in any other predetermined groupingorto follow .some definite geometric layout. hine 'of the presentconstruction the in twolcontiguous rectangularly positioned groups forthe-convenience of the operator f as willv hereinafter be explained, andeach-punch or group of punches will be directly associated or connectedwithv and identified by a definite key.

Another object of-thepresent machine is to denitely preposition an indexcard with the perforations thereof coincident with the plurality ofpunches but spaced therefrom, and to provide mechanism whereby inoperating certain selected keys, corresponding punches or groups ofpunchoperative position in relation to one side ofthe card, and toprovide a cooperative die block and associated mechanism which will bedisposed at the opposite side function as a means for bodily moving thecard towards 'and over the advanced punches to simultaneously notch theperforations which correspond to the advanced punches one punchingoperation. Another object of thepresent inventioneis the provision ofmeans for automatically feeding cards into the machine at the beginningofeach punching operation. The cards are disposed in a tray or magazineat one side of the machine before notching, while after notching and katthe end of each cycle of operation, the completely punched card willremain in the machine and from' the machine 1 by the next advancingunpunched card. One

card ,will always be in place in the machine but th'e same lmay,also beejected by feeding through a blank or otherwise unused or unpunchedcard.

The machine'is substantially automatic. in operation after the, keyboardhas been set up to code the card. Prior to the cycle vof operation,

cards are `fed froma magazine at one side of the 1 machine with thefront card supported in full view of the operator and also; positionedat onel sidev of the machine prior to. being `determined relation withrespect to the punching mechanism.

Another object of the present invention is to wherein thekeys, may begrouped for the convenience of ythe operator fed into `a pre- P theoperator will set upA the keyboard by pressing certain selected keyswhich lock in depressed position, such keys being selected according tothe l information which may be read from the front card in the magazineor tal and collateral information directly relating to that particularcard, and thereafter the operator pushes the control bar which sets themachine in motion for notching said front card of the magazine. Thecycle of operation after setting up thekeyhoard and pressing the controlkey is subfrom other supplemeni stantially as follows: The front card inthe magazine is advanced into the machine pushing the previous cardbefore it out of the machine; the key advanced punches are locked intoplace punches to be 'notched thereby; the card is then retracted oil' ofthe punches by a suitable stripper plate carried vby the die block and,finally, the machine is automatically cleared by suitable mechanismwhich releases the depressedv and latched keys of the keyboard andrestores the punch mechanism to its normal retracted and inoperativeposition. This notched card will subsequently be ejected from themachine by the next advancing card and in order that all of the notchedcards that are operated on by the machine may be elected therefrom, itmay be preferable to provide a blank card at the end of each stack ofcards in the magazine whereby the operation of such blank card willeject the last of the notched or coded cards.

Another object of the present machine is to provide a suitable spacerwhich may be inserted the space normally occupied at the upper Theremaining ments and for mechanical reasons as desired.

I'he spacer referred to is used to certain single punches orcombinations of punches thereby providing a means for notching one ormore cards in of course be governed by the exact shape of the template,and such cards may also be further notched by supplementing thecombination set up by the pre-setting templet by hand setting open orfree keys that are not affected by the templet setting.

Another feature similar to the foregoing is the provision of a templetof predetermined shape which may also be attached to and removed fromthe machine as desired, this templet functioning as a means lforblocking certain individual punches or groups of punches to prevent theoperation thereof when hand setting the keys. When a blocking templet isused, the keyboard is free for hand operation, but the keys directlyduplicate.- 'I'he duplication willA aseasu.

connected with the blocked punches shall be rendered inoperable by thelatter templet. The use of a mask that may be superimposed over thekeyboard and ings for permitting'the operation of certain keys is alsocontemplated.

Among some of the other novel features incorporated in a machine of thistype is the pro vision of e. repeating mechanism for automaticallynotching two or more cards with the same combination of punches as setup by hand on the keyboard of the machine. The machine is alsoconstructed to include a means for supplementing the automatic clearing'of the machine. By such a. means, the operator may at any time releasethe depressed keys which have been selected on the keyboard in case oferror or for any other reason that may require the releasing of thekeys.

All otherobjects and advantages shall hereinafter be referred to in thefollowing detailed description of the invention having specific ref.

board I2 having an upper group or rearwardlydisposedy set of keysyindicated generally by I3 with the.V individual keys designatedby Il;and lower-group of keysv extending forwardly of the machine andrgenerally indicated by the reference numeral Il with the individual keysindicated at I8. Eachof the groups of keys I3 and I5', respectively, areydivided intodecimal columns or row of .keys extending fore and aft'ofthe maner. The keybars are preferably arranged in groups of four abreastsubstantially as best shown in the diagram of Fig. 12 with each group offour bars underlying a column .of keys of the keyboard. 'I'he key bargroups are also segregated so that each grou-pcf four which cooperateswith one of the columns or rows of keys in the upper keyboard willcontain four bars such as I1 illustrated inv Fig. 13, while. the-groupsof bars which underlie the key columns or rows of the lower keyboardwill be four barslike I8 as in Fig. 14. It is also seen from Fig. l2that where groups of perforations are less than four in number, alsoreferring to-Fig. 1B showing the card, such per-- forations only needtwo bars which will underlie the rows having a smaller number of keyssuch as showninFig. 1. To aid'in arranging the placement of all ofthe'key bars I1 and I8, the upper columns or rows of keys I4 arepositioned in staggered relation to. the lower columns or rows of keysI6. This also aids the operator in set- Vtingup thefkeyboard fornotching a card.

The key bars -I1' are each provided with arms 22 connected with the rearends thereof while the key bars AI3 carry similararms 23, and all ofsaid arms are 4suitably bent'and shaped to connect with theslottingpunches 24 which are all slidably carried in the supporting plate 25mounted on the casing Iof the machine. The punches 24 are`provided withannular rings 26 and the ends` of the arms 22 and 23 are positionedwithin the annular rings 26 of the respective punches whereby thepunches move directly with such arms.

In Figs. 21 to 30 inkey, 31--No. 7 key, 3l-No. 8 key, I9--No. 9 key, and40 refers to the zero "0" key. These combinations prevail for eitherkeyboard of the machine and each row of keys from zero to No. 9inclusive is disposed in superimposed position with respect to eachgroup of four key bars, with the groups of key bars relating to theupper columns of keys being of the kind illustrated at I1 in Fig. 13,and with the groups of key bars relating to the lower columns of keysbeing of the kind illustrated at I8 in each column of the upper andlower keyboards respectively, and the movement of any one key Will causethe linger or lingers carried by said key to contact one of the lugs ofits corresponding key bar, thereby actuating said key bar or key barslongitudinally of the machine to advance the punch 24 or lpunches 24corresponding to said individual or combinationcf bars actuated.

` Upon operation of any key, such as .carries any into operationrelation, namely, in a position projecting beyond the rear surface ofthe 'supporting plate 25. Also by operating any of the keys illustrated`in Figs.y 25 to 29 which correspond to the key markings oi' 3, 5, 6, 8,9, respectively, each key by its corresponding combination oi' fingerswill actuate two bars simultaneas at 4I and 42, respectively, forlatching the bar operating lingers to hold the depressed keys in theirdepressed positions whenever operated. This latching eifected by theaction of the comb spring 43 which is suitably secured to the casing I 0of the machine transversely thereof with each of the individual fingersof/said springv engaging one of the plurality of key bars within the inthe supporting plate 25. r

Each of the key bars I1 and I8 carries one cam lug 45 and 46,respectively, which corresponds to the zero 0 key of the keyboard andthis cam punches into operative relation with respect t0 the supportingplate 25. Since the lugs 45 and 46 of the key bars I1 and I8 are notundercut, the zero key, finger 40,'shown in Fig. 30 will at the upper orlower spending group or four key bars and may be considered assupplementing the total clearing mechanism which eventually clears theentire operation of said machine.

The backing plate 91 is bodilyslidable upon lthe pins 12 and 13 which 'are conveniently carried by thesupporting plate 25. In connection with the punches 24. it should alsobe noted that their Apunching 'ends or cutting edges are preferablytapered asat 14 best illustrated in Figs. 2 and 15, for the purpose ofcausing a gradual shearing of the card during the notching operationinstead of a sudden collective impact by all the punches such as wouldoccur in thek event that the cutting edges of said punches had beendisposed in planes parallel to the face of thecard.

Referring now to Fig. 2, a die block 15 is provided with apertures 16which are aligned and shaped to receive'the punches during the'notchingoperation. This die block is movably related with respect to the casingof the machine and is oppositely disposed from the supporting plate 25and punches 24 ina manner clearly illustrated in Figs. 2 and 4.' `Astripper plate 11.v suitably secured to the, lower end of the die block15 is spaced therefromtoform a card space 18 between thestripper and dieblock into which space the cards are automatically fed for the purposeof being notched by the punches 24. The lower edge of the cards C, shownin Fig. 2 is guided by any suitable means for positioning the card "inproper vertical relation with respectto the four rows of punchesrectangularly arranged as shown` in Fig. 4. As seen inFig. 2, thestrippersis provided with an odset shoulder as at 19for closing the gapbetween the stripper plate and the die block for the purpose of securingtheV stripper plate to said dieblock and for the purpose of guiding andsupporting the lower edge of the index cards as the'latter pass into andout of the machine. Obviously, the stripper plate is provided withcorresponding apertures as shown at80 in Fig. 4 for the purpose ofaccommodating the punches 24 as relative movement koccurs between thepunches and the die block for the purpose of not'ching the cards. Thestripper plate moves blockas thelatter advances a card toward thepunches to be notched by the respective punches that have been advancedinto operative card notching relation.

There are various ways injwhich the index cards may oe-advanced intojthe machine and discharged therefrom. but in the present ma-y chine asbest illustrated in Figs. y1 and 3, the magazine A8| for Vholdingandsupporting the index cards is located at the left-hand side of themachine and in a, position wherein the operator can'read the datacontained upon the cards for the purpose of setting up the keyboard fornotch- The magazine 8| preferably comprises a container or trough 92having a window 81aat one side and a suitably supported plunger 83slidably carried by the wall 84 of the magazine and the supported 85.Any form ofy resilient means such wall 84 group forwardly and theplunger 83 for urging the card in the magazine 8| of the machine andinto aligned relation with respect to ofY operation may revolutionclutch 93 by means of the drive roller 94 on the motor shaft whichkenyedge of the card'and Vpose ofl advancing the left-hand verticallydisposed punches as best which 'is adapted for contacting the outermostto move the same towards and into operative punching relapunches and dieblock.

the machine tion with respect to the Theprongs 90 of the card to themedian line of illustrated in Fig. 16 and the length of the feed strokeof the bar 88 and yfinger 89 is definitely controlled by the mechanismutilized for advancing rod 88. The card will stop r,and be frictionallyheld Within the card space 18 at the end of the stroke of said cardfeeding mechanism. Theiinger 89 is also adjustably carried on the rod 88by means of the screws 9|a.

The drive of the machine to perform its cycle be accomplished in variousways. In the construction of the present machine, an electric motor 9|is utilized for constantly Ldriving .the inertia wheel 92 of a oneconical gages the peripheral lip 95 of the inertia. wheel 92 of the onerevolution clutch. The clutch utilized is illustrated more in detail inFigs. 6 and rI wherein the inertia wheel 92 carrying the lip 95 isadapted and suitably connected for constantly driving the star wheel 96which is freely rotatable together with the inertia wheel 92 the cardspace 18 ofv Fig. 2, such position of rthe Y upon the main drive shaft99 of the machine. A disc 99 carrying a suitable dog |00 is keyed to theshaft 98 by means of a pin |0| and the spring |02 acts to keep `this dogin driving engagement with respect to the star wheel 96. As best viewedin Fig. 6, the trailing end of the dog |00 is provided with a cam |03engageable by a roller |04 pivotally carried by the arm |06 which may bemoved laterally with respect to the face of the clutch by means of thepush rod |06. The rod |06 is connected at |01 to a bell crank |08.` andthe bell crank is operated by the stem |09 suitably connected with themachine operating key' ||0 as best shown in Figs. 1 and 2. By depressingthe operating key ||0, rod |06 is moved laterally Vwith respect to theface of the clutch through the bell crank |08 so as to move the roller|04 laterally out of the path of the cam |03 whereby the dog |00 willmove 4into operative engagement with one of the teeth of the revolvingstar wheel 96 to be directly driven by the motor 92 as hereinbeforedescribed. Obviously,.the release of the operating key ||0 willimmediately allow the roller |04 to reposition itself by'means of thespring intothe path of the cam |03, so that the dog |00 will again betripped out of operative relation with respect to the star wheel 96,after one revolution of the clutch has beenv completed.

During the single revolution of the clutch 93,

A vsecond roller |68 is mountedfor frictionally contacting thezface of each card beingv discharged andis driven by means ofthe belt |69 and pulley |10'.A Cooperating withthey roller |60 is the plater |1| disposed to normally main-`r tainY thecards in voperativecontacting position with respect to the wheel |68;Preferably the l peripheralfspeed ofthe wheel |88 is greater than thelinealspeedlofzthe discharging card whereby saidxcard istpulled out ofthe machine and de-v posited in suitable traysor other means as desired.Obviously, .thisV extra feed mechanism by each: next advancing templetas shown in Fig. 31 andas indicated at |14 is provided with .suitableprojections or teeth |15 all located in a predetermined arrangement andbeing positioned opposite the ends of certain single or grouped barssuch as |1 and |8. Each of the presetting vtemplets isprovided withsuitable slots |16 for placing the same over spaced studs |11 which aresecured to the front face of the casing |0 of the machine. Suitableknurled nuts |18 are provided for moving the templets against theprojecting ends of the key bars whereby all of the key bars engaged bythe projections or teeth |15of the presetting templet shall be movedrearwardly of the machine from the position shown in Fig. 10 to theposition shown in Fig. 11. punches into operative notching relation withre' spect to the cards to be notched. Also, other keys may be depressedwhich are not affected by the presetting referred to.

The blocking templet as illustrated in Fig. 32'

and indicated at |80 is similarly provided with projections or teeth|8'|, but it is to be noted that in the blocking templet theseprojections are reversed and depend downwardly instead of projectingupwardly as do the projections |15 of the presetting bar |14. Theblocking bar is also provided with suitable slots |82 for engaging thestuds |11 so that the bar may be secured in place by the knurled nuts|18. However, the projections |8| of the blocking templets are adaptedto renter the notches |83 of the key bars, such notches being positionedflush with the outer sur face of the front wall of the machine, so thatthe depending lugs |8| will lie within the notches |83. Thiswill preventthe operation of any of the keys associated with the key bars which areblocked by the blocking templet, leaving free however, any 'of the otherkeys which are not affected by this relation. j Y

All of the foregoing description has been dii rected to the normaloperation of the machine ing member |90 having an edge adapted to liecould'bevdispensed with Iin theory if the punches at the right-handsideV ofthe machine are made single or oneA sided punches instead ofdoubley sided punches in ywhich case the card which has been moved outof the machine may remain in contact. withthe: leading ledge of thefollowing card to'be punched, ywithout interference or action by any ofthe right-hand vertical row of punches.- f l To supplementthe r guiaroperation ofthe machine, certain templets in the form of blockingV andvpresetting templets may be'employed for ini` tia-lly blocking :theoperation of certain key bars or vice versa for initially advancingcertain -key bars and presetting a numberv of the punches for definitelynotching a cerdas per` the combina tion of the presetting templet. Forthis purpose,- the front-wallof they machine as best illustratedv inFig. 8 has been' provided with suitable aligned openings |13` forpermitting the forward endsvof the key barsto project 'therethrough inthemanner illustrated in Figs. 2 and `10. The. presetting `otherreference markings may in the median plane of the upper horizontal rowof punchesy to support other sized cards. so that thetlatter can also besuitably notched. The spacer may be a fiat solid rectangular piece ofcardboard or the like and may or may not be notched for clearance. Thespacer illustrated is provided with depending legs |9| notched as at |92for the purpose of enga-ging the rod |06 at one side of the machine anda suitable pin |93 at the other side of the machine for definitelypositioning said spacer. A suitable handle |94 may be extended from oneleg for the purpose of hand-settingsaid spacer into the positionreferred to. 'Ihe .upper end of the spacer is also notched as at |95 forthe purpose of clearance to avoid being contacted by the lower halves ofthe upper punches. Suitable cards such as shown at |96 in full linesyand at |91 in broken lines may then be individually positioned upon thespacer to have the lower edges thereof notched forthe pur-pose of codingsaid cards. Obviously, be made on the machine itself or other suitablepositioning clips or guides may be employed for placing the cards |96and |91 in their proper lateral relation with respect to the width ofthe machine and with respect to the punches.y Also, when utilizing a|89, the feed finger 89 may be spacer such as Obviously, this willadvance certainsimultaneously causing released from the feed rod Il orother suitable disconnecting mechanisms may be employed to preventoperation of the reed finger Il that is only utilized with the 3% indexcards. For the purpose of further accommodating large cards with thespacer |89 in place, the upper horizontal row of punches has beenextended as at |91 and |98 in Fig. 12 and the cor responding'punchopenings are well shown in Fig. 4.

Although the spacer |89 may be used as described for both large andsmall cards, it is primarily for the purpose of supporting cards of lessheight than the standard card height thereby hold the same in a raisedposition accessible to the hand. All cards of a greater height than the3% inch height of the standard card and which are high enough to -behand positioned in the usual card space 18 of the machine, can besupported on the ledge 19 and notched with the lower row of punches.

`It is obvious that various modications may be resorted to in theconstruction of the present machine. Therefore, the preferred form.ofthe present device should only be limited to the general arrangement andcombinations of part.: disclosed as shall be governed by the breadth andscope of the appended claims.
